Question

Solve for x. The polygon in each pair are similar

Answer 1

x = 7

Explanation:

To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

`(4)/(8)=(-7+2x)/(14)`

Find x by cross multiplying numerator and denominator of each fraction.

4(14) = 8(-7+2x)

56 = -56 + 16x

112 = 16x

7 = x
